Google Maps shows enhanced local search results. Compared to the previous format, Google Maps lets you find more information about the local businesses without having to click on each result. You can see a thumbnail, an excerpt from the most recent review and a link that encourages to post your own review. This format was already used in the text view, but probably few people noticed it.
Excerpts from reviews are included in local search OneBoxes as well, but Google chooses different reviews. Judging from these changes, I think businesses will start to upload images to the Local Business Center and will encourage their customers to post reviews to Google Maps or other sites.
